If you recently had your battery replaced, this could be the reason. I just had the same problem. Ended up that I had to have my fuel injection system cleaned. Cost a few hundred dollars when it was all said and done.

Will a 01 eclipse wire harness work for a 03


Possibly, it all depends on the ECU and engine sensors. The only way is to get a workshop manual and check all the connections. Mitsu often change sensors and connectors between years.

My car keeps cutting off as soon as I take my foot off the gas. It fires back up when i crank it and idles fine but as soon as i release the gas it cuts off.


Try some octane boost. if that dose not help it can be your Fuel pump, one of your spark plugs, or a coil pack. the idling up and down can also mean bad timing i would have your car looked at but you can try the above first

2003 toyota highlander will not idle, must keep foot on the accelerator to keep engine running. AS soon as my foot is removed from the accelerator the engine cuts off.


The first place I would look is the IAC motor (idle air control) usaully on throttle body and possibly dirty throttle body and one last thing could possibley be EGR valve exaust gas recir. as if it stuck open it will lean out engine.

Transmission rebuilt 5 years ago on a 1997 Eclipse RS. Now, the RPM levels are extremely high even without full acceleration.


The likely cause for your high RPM may be caused by a vacuum leak in the engine. You can open the hood and check your hoses for cracks and leaks. This is a good place to start, but may no be a full solution.

Engine will not idle will cut off as soon as foot is off peadle


possible solution, there is an idle circuit on your mass airflow sensor that allows air to bypass the throttle plate. if this little actuator is not working then no idle air will be able to get by the throttle plate which then tells the mass air flow sensor that there is no air moving which in turn tells the computer to stop pumping gas into the cylinders...which make your car shut off. hope this helps, cheers
